How to Install a Knock Sensor on a 3.7L Engine on Dodge Nitro?

When you install the knock sensor for the 3.7L engine, recognize the sensor on the left by its (LEFT) tag and the larger bolt, since this ensures the PCM checks only the proper locations in the vehicle. Make sure you clean the knock sensor's mounting holes before you install the sensors in the cylinder block. Avoiding misadjustment of the sensor mounting bolts is important, since it may negatively influence the operation of the knock sensor and spark control; therefore, the bolts should always be tightened with 15 +/- 2 ft.lbs. (20 Nm) (176 in.lbs) with the specified tool. Remember, the foam strip on the bolts helps hold them during the assembly of the plant and should not be seen as a sealant; do not treat them with adhesives, sealants or thread locking compounds. After finishing the tightening, link the knock sensor wiring to the engine harness found at the back of the intake manifold and you can now add the intake manifold.

The Knock Sensor in Dodge Nitro vehicles always assist in the performance of the vehicle by identifying situations when the engine knock exist due to improper ignition timing. It signals the powertrain control module (PCM) to allowing the PCM to correct the ignition timing to reduce prone detonation. Usually, Dodge Nitro uses piezoelectric knock sensors which converts the vibrations into electrical signals so as to enable constant analysis of pressure spikes which signify knocking. On occurrence of knock, PCM reduces the ignition timing by small amounts until normal combustion occurs, and then the timing is gradually returned to normal. This process enables the preserves the operating efficiency of the engines at the same time, limit their exposure to damage especially with low octane fuels. The fact that the system takes the role of optimizing ignition timings per cylinder adds to its efficiency; it meets the demands of the engine when in use.
